Referring firstto Figure 1, the numeral I0 indicates a blank which may be made from a sheet of cardboard or the like. The particular blank chosen for illustration is intended for a carton having uniform rectangular cross section throughout its length with end Walls disposed in right angular relationship with the side walls though the invention is equally applicable to cartons having tapering walls, that is, cartons of the nesting type, as illustrated, for example. in applicants Patent No. 2,390,909 patented December 11, 1945. Secured to the under surface of the blank as illustrated in Figure 1, which will be the inner surface thereof when the blank is shaped into a carton, is the liner Il. Said liner will be adhesively attached to the blank I0 throughout the area of said liner except at regions adjacent to the crease lines of said blank, as will be explained presently.

The blank I0 chosen for illustration is -generally rectangular in outline, the top and bottom edges lying in the parallel lines IIIA and I (IB respectively. Said blank has the parallel side edges I2 and I3 and is provided with the spaced crease lines Il, I5, I6 and Il. Crease line I4 is spaced from the side edge I2 and the crease line I6 is spaced from the crease line I5 to provide either the front or rear wall of the carton. Crease line I5 is spaced from the crease line I4 and the crease line I1 is spaced from the crease line I6 to provide each of the two opposite narrow side walls of the carton. The space between the crease line I'I and the edge I3 is a connector section and is utilized for securing the blank into a continuous outline rectangular in cross section. The part of the blank Ill between the edge I2 and the crease line I4 provides the relatively wide wall or panel I8, referred to hereinafter as the first Wall or panel. The portion between the crease lines I4 and I 5 provides the relatively narrow wall or panel I9, referred to hereinafter as the second Wall or panel. The portion between the crease lines l5 and I6 provides the relatively wide wall or panel 2li, referred to hereinafter as the third wall or panel, and the portion between the crease lines I6 and I1 provides the relatively narrow wall or panel 2i, referred to hereinafter as the fourth wall or panel. The portion between the crease line Il and the edge I3, indicated by the numeral 22, is a connector section and is 3 adapted tobe adhesivelyseeured tothe wall or panel Il.

The top and bottom edges of panel Il (the rst panel) are dened by the crease lines 25 and 2|. respectively. The top and bottom edges of the panel il (the second panel) are defined by the crease lines 25 and 2l, respectively. The top and bottom edges of the panel (the third panel) are defined by the crease lines 21 and 25. The top and bottom edges of panel 2i (the fourth panel) are defined by the crease lines 2l and lll. The top and bottom edges of the connector section 22 are denned by the crease lines Ii and 32, respectively. The crease line 21 will preferably be disposed slightly higher than the crease lines 2l and 2l. the crease lines 25 and 2l being in alignment with each other. The crease line 3i may be in alignment with the crease lines 2S and 2l. The crease line 23 will preferably be slightly lower than the crease lines and 29. These diderences in the levels of the crease lines 25, 25, 2l. and 2| will facilitate the folding of the top closure, as will appear presently. The difference in level of the crease line 21. with respect to the crease lines 2B and 22, will be approximately twice the thickness of the material of the blank. The level of the crease lines 25 and 29 will be spaced above the level of the crease line 23 approximately the thickness of said material.

The portion of the blank below the crease lines 24. 25 28. Il and 32 will provide the bottom closure of the carton. The details of this bottom closure form no part of the present invention but are described and claimed in applicants copendine application Serial No. 150,954. filed May 28. 1947. However, the bottom closure of the carton may take any preferred form as, for example, that disclosed in Patent 2.390 909 dated December il, 1945; or the top closure described and claimed in this application may be used if desired.

The crease lines Il, I5, l5, I1, 22, 21 5I, 2l. 2B, 28, 2U and 52 will be ruled into the blank Il on the undersurface thereof as the blank is viewed in Figure l so that said crease lines will bias the parts at the sides thereof to bend inwardly, that is toward the bottom side of the blank as viewed in Figure l. Crease lines 25 and 28 will be rued in from the top side of the blank as viewed in Figure 1. In this disclosure those crease lines ruled in from the bottom side of the blank will be indicated bv plain solid lines whereas, those crease lines ruled in from the upper side of the blank as viewed in Figure 1 will be represented by solid lines having dots spaced therealong. Crease lines ruled in from the bottom side of the blank whereby to bias the parts thereof to bend inwardly wil be referred to as direct crease lines. Those crease lines ruled in from the top side of the blank as viewed in Figure 1 will be referred to as reverse crease lines.

Located above the panel Il and swingably connected thereto along the crease line 23 is a flap 33 having the edge 24 (offset slightly toward the right from the edge I2) the edge I5, the edge 3B. and the crease line 31. Said edge 56 and crease line 31 are in augment with each other but are offset slightly toward the left from the crease line H. Y

The panel 2l (the third panel) is provided with the ilap Il swingingly connected thereto along the crease line 21. which flap Il is defined by the crease line 21. the crease line 30, the edge 40 and the crease line Il. Said crease lines are set inwardly slightly from the crease lines l! and It respectively. Extending from the left end of the iiap Il is a web 42a which terminates in the tab l2 and extending from the right end of the nap 2l is a web 23a which terminates in the tab Il. Said tab I2 and web 42a nre [is] dened by the edge Il extending from the juncture of the crease line Il and the edge III in 45 degree relationship with the edge lll; the edge Il; the edge II; the edge l1 and the crease line Il. Said crease line Il is disposed in 45 degree relationship with the crease line 25 and communicates with the intersection of crease line 25 to crease line l5. As indicated above, the crease line 35 is offset slightly toward the right from the crease line I5. The edge u and the crease line 45 terminate at the broken line 4l. The region bounded by the edge M. the broken line 4l, the crease line 45 and the crease line I9 [is a] constitutes the web [indicated by the numeral] 42a.

The tab l2 and web 43a extending from the right hand extremity of the nap I5 [is] are symmetrical with the tab I2. Said tab 43 and web 43a are [is] defined by the edge 51| extending in 45 degrees relationship with the edge l0 from the juncture of edge 40 with crease line ll: the edge 5I: the edge 52; the edge S2; crease line I4 and the crease line 4|. The edges Eil and 54 terminate at the broken line 55. The region bounded by the edge 50; broken line 55; crease line 54 and crease line 4l constitutes [a] the web [indicated by the numeral] 43a.

Joined to the ap 32 at the right end thereof is the web 55 dened by the crease line 51; the edge 51; the edge 58 and the crease line 59. Said web 5B is joined by means of said crease line 59 to the web B0 joined to the panel I9 (Second panel). Said crease line 59 extends in 45 degree relationship with the crease line 25 from the juncture of said crease line 25 with the crease line il. The web 56 and the web 60 provide a web-corner. and the web tu and web 42a provide another webcorner. which web-corners contribute to the siftproofness of the top closure of the carton.

The connector section 22 is provided with the flap 5I which is defined by the edge i5; the edge 62; the edge B3; crease line 'il and the edge 3l. The edge B3 and crease line B4 are in alignment with each other but are odset slightly toward the right from the crease line i1 to facilitate folding of the top closure. i

Swingingiy connected to the panel 2| is th web defined by the crease line 29; crease line 54; edge 66 (which lies closely adjacent to the edge 53) and crease line 81. Joined to the web 65 is the web Bl projecting from the side of the flap 8|. Said web 62 is defined by the crease line 61; the edge 69; the edge 1l and crease line 6I. The crease lines 54 and 61 are disposed in 45 degrec reationship with the crease line 29 Aand the extremities of said crease lines M and 61 communicate respectively with the juncture of crease line 29 with crease line I6 and the juncture of crease line 29 with crease line i1. The webs a and B5 and the webs B5 and 68 provide webcorners contributing to the sift-proofness of the `upper closure of the carton.

The present invention contemplates the provision of a liner for the four side walls of the carton which liner is indicated by the numeral Il in Figures l, 2 and 3. Said liner will-beprovided with a series of sets of score lines. each of said sets comprising a center score line indicated by the numeral Il and a pair of score lines 'I2- 12 parallel withbut spaced from the center score line 1I. Each score line 1I is intended to be located in juxtaposition with a crease line I4. I5 or IB of the blank I0. The liner II will be adhesively secured to the inner wall of the blank (that is, the under side as the blank is viewed in Figure 1) but the regions adjacent to each center score line 1I between the adjacent score lines 'I2-12 are left free of adhesive in order that no rupturlng of the liner or of the adhesive between the liner and the blank III will occur when said blank is bent along the crease lines I4, I5 and IB.

The mode of operation of the above described embodiment of the present invention is substantially as follows:

Blank I0, as illustrated in Figure l, may be readily bent along the crease lines I4, I5, IB and I1 into a substantially rectangular contour. The connector section 22 will be located inside of the panel i8 (the first panel) and said connector section will be adhesively attached to the side of the panel I8 to provide a tube of approximately rectangular cross sectional contour. The flap 6I will also be adhesively secured to the flap 33.

The bottom wall of the carton below the crease lines 24. 26, 28, 30 and 32 may be folded to provide a closure for the lower end of said tube, the details of this closure forming no part of the present invention. 'I'he carton thereby provided may be iilled with material after which the top of the carton may be closed. The preferrred procedure in closing the top of the carton is as follows:

The upstanding flap 33 is swung inwardly about the crease line 23 as an axis into right angular relationship with the wall 28 carrying with it the ilap BI adhesively attached to said flap 33. This action will swing the webs 65 and 68 about the crease line 81 and will swing the webs 56 and 60 about the crease line 59. The flap BI as well as the flap 33 will fit within the top of the carton, forming a strut between the wall I8 and the wall 2li thereof. The web 56 will be swung into flatwise engagement with the web 60 and the web 68 will be swung into flatwise engagement with the web 65, said webs 56 and Iill at one side of the carton and said webs 6B and G5 at the other side of the carton being swung outwardly with respect to the carton (Figure 5).

The flap 38 will then be swung downwardly into flatwise engagement with the nap 33 whereby the parts will assume the positions illustrated in Figure 6. Adhesive will be used between the contacting faces, that is, the interfacial surfaces of the flaps 33 and 38 whereby said flaps will be secured together.

An important feature of the present invention is embodied in the eilicient sealing of the webs 68 and 65 with the tab 43 (that is, the web portion 43a of said tab between the lines 4I and 55), as well as the efficient sealing of webs 5B and B9 with the tab 42 (that is, the web 42a thereof between the lines 39 and 49). Adhesive having been applied to the contacting surfaces. said webs 68 and 65 will be secured together and to the flap 43 and the webs 36 and 60 will be secured together and to the flap 42 by squeezing or gripping actions. The tabs 42 and 43 will then be drawn down into engagement with the panels I9 and 2l, respectively, drawing the top flap 38 tight across the top of the carton. At this time sealing pressure is applied across the top of the carton, tightly sealing the nap 38 to thetlap 33. The tabs 42 and 43 are securely attached to said panels I3 and 2|.

By reason of the adhesion of the webs Bl, Il, I3 and ill with their corresponding tabs 43 and 42 a tight sift-proof seal is had. Byreason ot the liner II extra side wall rigidity is provided so that an appreciable amount of pressure may be applied in the sealing operation without collapsing the carton.

The invention provides a carton which provides considerable rigidity, the rigidity being improved by reason of the laminated construction embodied in the material of the blank Ill, the liner II and the adhesive film therebetween. All edges through which line grained material may attempt to seep will be tightly sealed and a closure is provided which has uniform thickness. By reason of the novel liner arrangement, the required rigidity is attained without the necessity for using heavy materials. Said liner may be attached to the blank when said blank is in flat condition and may be folded up with the blank without danger of rupturing of the liner or of the adhesive material between the liner and the blank.

Though a preferred embodiment of the present invention has been described in detail, many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.
